It turned out to be due to that Perl got updated and by default perl disables SUIDPERL. I tried several things to activate it like configuring /etc/make.conf but it didn’t help.
This is how I solved it:
make config
And chech SUIDPERL and then make
make showconfig
to make sure it is set.
To build and reinstall do:
make deinstall make reinstall
Turned out the above even didn’t help, though found this which finally solved it. Not so easy when there is a bug in the code!!
It’s been reported officially too.
